I am a licensed siding contractor with more than thirty years of siding experience. I have used dozens of different sealants over the years and this is the sealant I've been using for the past several years.
Quad Max is a class 50 sealant and probably one of the only ones available at HD. This means it allows for 50% expansion and contraction where other sealants are only a class 25 with 25%. This helps it stay attached under the strains of weather and temperature.
Don't confuse Quad Max for the regular Quad sealant which can be hard outfoxed the gun, smells terrible, and is defiently hard after it cures several days later- and shrinks. By comparison Quad Max has little odor compared to most sealants, cures and paintable in a couple hours, and comes in many color matched colors from Hardiplank pre-painted siding, to vinyl siding or many window colors. The cartridge is plastic so it holds up to wet conditions where cardboard ones will blow a hole in the side if it gets wet. The tip screws off so I can reuse the tip and save the new one for a different sized sealant bead. There are other good pro sealants but this one meets all my needs.
As to applying the sealant it should come out hard out of the gun. If it does you either have an old tube or you aren't using QuadMax. After going through hundreds of cases of it I can only remembers couple times the sealant had firmed up. Check the date on the tube before opening.
Most sealants should be applied to a wet surface if you want the joint to last. Damp surfaces are ok since it's a moisture cure sealant and will draw the moisture out. Applying sealant well takes lots of practice.
Each sealant has different gunning characteristics. Apply masking tape on both sides of the joint, smooth the sealant and pull the tape for a clean joint.

Excellent product. I have move away from the DAP line of product and exclusively using the OSI family of sealants without any issues or regrets. I find this QUAD Max extremely easy to use and very reliable when applied correctly and in the correct circumstances (temps, weather conditions, etc) I do know other contractors that have issue with the colors in the QUAD Max family not being as close as they would like but I have as of yet to experience anything of this nature. I will continue using this product without hesitation and know that I can count on it to perform as intended for many many years to come. I have not had a single call-back due to product failure since converting over the OSI family of products.

I have very mixed feelings after going through a case of this stuff. It is very creamy and flows easily, when the temp is above 45 degrees F. That is both good and bad. If your gap is small it is ideal and gives a nice look between siding and trim. But if the gap is larger then the stuff kind of goes all over the place as you try to smooth out your bead. I prefer TX 1 for bigger gaps, although this appears to shrink a little less. Under 45 degrees I had this ball up and skin over pretty quickly and it did not spread well at all. Note that it was not old stock, as I went through the packages on the sales floor checking dates and found a six-month range in dates on those being sold. Perhaps it is just that I'm used to the heavier-bodied TX 1 and NP 1, but this is kind of like a very creamy yogurt, and I didn't expect to ever say this, but it flows too easily. I've heard the non-Max version is a bit thicker and perhaps give some of that a try. This isn't bad, and I might use it again, especially for narrow gaps where it is quite good

when you get it out of the tube it does what it says
3 out of 12 unusable... broke seal but would not flow out except from the bottom... ruined caulk gun
definitely for pro use only... unless you like working with marshmallow cream like sticky mess that can only be cleaned up with mineral spirits

I liked it for installing triple-pane, soundproof windows with nailing flanges. Came out with a gun easily at 65 degrees. No problem working it and smoothing it as long as its done within maybe 15 (minutes so it doesn't skin over) so one has to work relatively quickly. Year and date of manufacture is on the tube, so buy fresh tubes and look on the shelf, as almost no store these days rotates their stock appropriately.

Extremely flexible and durable! Messy for newer users but take your time it’s a fantastic product the won’t flinch at the elements. Worth every penney when you want to do it once and do It right the first time.
This is a great caulk, went through two cases already on my siding and windows. Really nice given my climate that it can be installed down to 0 deg F. The less expensive water base caulks need warmer temps. It also hardly shrinks when the water based caulks require two applications given how much they shrink. It will give you a forearm workout so get a good gun.
this caulk is the best i have ever used, it is made to stick to plastic and it does,
but it is just such a tough flexible caulk for just about anything. not sure about
wood, but metals, plastics- its better than sikaflex, and sikaflex is superb.

Great coverage, easy to seal gaps on the new siding I installed on my house. A standard caulk gun will not suffice for application. Get a caulk gun that has a higher mechanical advantage. I got one that was a 12:1 MA, and it worked well.

We inherited a caulked deck (never wouldn't have caulked if I'd built it myself...!). Not too pretty now, but this repair will get us through the winter, and then we'll finish stripping the paint next spring and stain the deck. The space below is staying dry so far. Fingers crossed! Strongly advise using a power caulk gun to apply, as it's stiff and thick.
